The Denver Museum of Natural History recently suspended regular use of toxic fumigants in the zoology research collections and substituted an integrated pest management program consisting of specimen monitoring and localized fumigation of infested cabinets. A bird conservation survey provided baseline information on the physical condition of specimens in the collection, evidence of dermestid beetles, and targeted specimens in need of conservation. The museum also expanded protection of exhibited zoological specimens by instituting systematic conservation audits, basic cleaning, and pest management, involving regular monitoring and use of low-toxicity insecticides and insect traps in dioramas.
